WITH a grand French-inspired stone manor, a helipad, wild deer, a 500-tree orchard and a $20 million price tag, Chateau Le Marais could be the state's most glamorous fishing retreat.

The 105ha estate on Wallis Island, less than 15 minutes by boat from the mid-north coast town of Forster, about 300km north of Sydney, is just one of several land parcels for sale.

Chateau Le Marais is a 15-year labour of love for former Woollahra antiques dealers Andre and Cecile Fink, who reportedly snapped up the once virgin island parcel in 1996 for a modest $290,000.

Although the price tag has not changed since agent Andrew Huang of Harcourts Chatswood listed it 11 months ago, he said the luxury dwelling is now almost complete.

"It's probably about 95 per cent done. Someone just needs to come in and buy it and finish off the CBUS (wiring), satellite TV and other electronics to their standard and it will be ready," he said.

The estate has its own electricity generation system, solar panels and is considered self-sufficient.

A hybrid of Australian and European design, the neo-classical five-storey chateau has intricate stone masonry inside and out, parquet floors modelled on Versailles, a games room, conservatory and comes with an orchard, a flat savannah, a private jetty and a 1.5km personal beach.

Mr Huang said the rare island listing is also a private nature reserve.

The Finks' estate adjoins a 584ha national park on the island.

On the opposite side of the island there are three land parcels with an asking price in the "high $1 millions".

Daniel Cross of Ray White said his triple listing on the north side of Wallis Island, which totals approximately 140ha, includes one 100ha block with a 1.5km army-grade air strip and old hangar on site.

"A few decades back the army landed a Hercules there, so it can take some serious aircraft," he said.

The northern side of Wallis Island also houses a handful of dwellings, many with private jetties, where the median house price is $500,000.

But as far as an eco tourism venture is concerned, Mr Cross said previous residents had tried and failed.

"People have done the feasibility studies for creating eco tourism on the island, they've made applications and got nowhere fast so have just given up," he said. "If I had the money, I'd buy it myself. It's only about 10 minutes in a tinny to Forster-Tuncurry to go to work."
